The minister said that officials from the Environment and Resources Authority and the Fisheries Department were at sea today, carrying out inspections in connection with the slime reported in Marsaskala and Sliema.

"By tonight or tomorrow, I will have more information on the situation, and I will know which regulations have been broken. After that, I will see to it that a remedy is put into place," Herrera said, adding that such reports worried him.

Herrera said that when he introduced the policy that fish farms should be further out at sea, he anticipated that there would still be some cases of slime in coastal areas. "We had to mitigate the situation, but we cannot stop the fishing industry, However, if operators did not abide by the regulations, they have to pay the price," he added.

The situation came to a head in the summer of 2016 when slime from fish farms polluted bathing areas stretching from St Paul's Bay all the way down to Sliema and Marsaskala.

Herrera, who had just been appointed environment minister proposed new regulations that saw fish farms being relocated at a greater distance from the shore.
